Abstract

The invention belongs to the field of polyphenyl ether, and provides a solvent-resistant polyphenyl ether composition which comprises the following raw material components in parts by weight: 100-130parts of PPO and 30-64 parts of SAN. Wherein the intrinsic viscosity of PPO ranges from 33 cm < 3 > / g to 52 cm < 3 > / g, and the molecular weight ranges from 22000 to 57000; wherein the SAN has a meltindex of 10 to 35 g / 10 min (220 DEG C, 10 kg). The solvent-resistant polyphenyl ether composition has the beneficial effects that the solvent-resistant polyphenyl ether composition prepared by the method has the advantages of high solvent resistance, good mechanical property, easiness in processing and forming, relatively low cost, wide application field of products capable of being manufactured and the like.

Description

technical field [0001] The invention belongs to the technical field of polymers, and relates to a modified resin composite material, in particular to a solvent-resistant polyphenylene ether composition. Background technique [0002] Resin is a high molecular compound polymerized from monomers as raw materials through addition polymerization or polycondensation reaction. Modification of the resin to achieve the application of the relative field, adding various additives or blending modification with other resins, has become a wide range of technical means. [0003] Polyphenylene ether (PPO) is one of the five general-purpose engineering plastics in the world. The advantages of this kind of plastic are high rigidity, high heat resistance, flame retardant, high strength, wear resistance, non-toxic, pollution resistance, etc., so it is mostly used in manufacturing It is suitable for making heat-resistant parts, insulating parts, wear-reducing and wear-resistant parts, transmiss...
